Javelin is the award winning point and click tool for the design, coding, management and persistence of POJOs.

Javelin has been the world's most intuitive, easy to learn, lightweight, visual modeler/coder utilities for Java since 1996 because it makes developing object oriented code so natural, easy and efficient. It takes care of all the underlying java source files and presents you with an uncluttered, intuitive visual representation of your model and code where you can concentrate on designing and coding classes and the relationships between them visually instead of battling through a sea of text files and navigating package directories. Javelin uses UML notation for its class diagrams but that does not mean that Javelin is a UML tool or that you have to know UML to use the tool - which makes it most unlike typical heavyweight UML tools.

Model driven software development - it's all about classes and their relationships

Simple mouse operations are used to create or edit classes, attributes and methods. That's fairly standard stuff in most text based IDE's but Javelin supports this in a 2D "live" class diagram. Where Javelin really shines, however, is in it's ability to know about and manage relationships. Drag and drop between class icons to create inheritance (extends) or association relationships. Right click on one end of an association relationship to change the properties at that end of the relationship such as cardinality (0, 0..1, 0..m, 1..m), the relationship name/role, code generation directives and object/relational mapping directives that determine the code generated in the automatically generated mapping files for Hibernate or JDO (whichever persistence technology has been selected in the persistence options).

The sophisticated, expressive, real life object models that make up the M in modern MVC applications typically involve many relationships between classes. If you can manage your relationships at a higher, visual level with a judicious use of automation then you will realize tremendous improvements in model comprehension, developer efficiency and reduce development time. Javelin is your key to higher developer productivity with its high level, automated relationship management.

Lightweight, full life cycle, non invasive

Javelin is full life cycle, two way, zero time synchronization modeling tool: you can freely modify the source code of a method from within Javelin or do it from outside Javelin� in your favourite IDE - either way is fine because Javelin keeps the source files synchronized with the design in zero time and without explicitly invoking an export/import process, saving you time and effort. Javelin only stores, in it's highly optimized internal database, structural information like class names, method signatures, attributes and relationships but not method source code. The source code of methods remain in the java files themselves making it possible to make changes to method bodies from external tools without needing to invoke a separate import/export process when switching between design and coding activities. In this way Javelin becomes a light weight, non invasive, full life cycle modeling/coding tool unlike many heavy handed modeling tools that want to "take over" your entire development process.

Self documenting models

Used throughout the development life cycle Javelin class diagrams form "always up to date", "live", "self documenting" project artefacts that make it easier to bring new developers on board and have existing developers understand each other's work in the project's object model.

Features:

Easy to Use, Intuitive interfaceInstallation is quick and you can master Javelin's intuitive user interface in less than 20 minutes using the 'Getting Started Tutorial'. Extensive use of right mouse button click makes operations easy and fast!

Integrated Hibernate SupportNow creating the mappings from your beautiful object model to a relational database via the Hibernate persistence service is virtually zero effort. Just as Javelin manages your .java files it can now automatically manage the mappings to Hibernate.

Automatic addition of setter/getter methodsNow you can forget writing setter/getter methods by hand. Javelin asks you if you want it to create them for you whenever you add a new attribute. "Do you want fries with that?" says the ever so loyal modelling tool

Class ListerFor larger projects finding that class has never been easier.

Robust and Industry ProvenJavelin is based on the same core technology as our robust, industry proven, visual object oriented development environment for C++ called Visual Classworks which has been serving the C++ community for more than a decade.

Easily Invoke Sun's JDK Java compiler...A single button press compiles only files that have changed. Another tool bar button executes Sun's AppletViewer, Java� run time or any other program you like.

Java� Import FeatureWant to be more productive with code that you have already written by hand? Then simply import existing Java� code into Javelin in a jiffy! From then on you can enjoy all the productivity and documentation benefits Javelin has to offer

UML Based NotationDevelopment with Javelin is carried out in a "live" class diagram. The notation of the class diagram notation is based on the UML "standard" for class diagrams. Take advantage of the latest advances in object oriented technology with Javelin

The automatic importing of dependencies of the immediate abstract base class and immediate interfaces now extends recursively to include the dependencies of all abstract base classes and interfaces in the hierarchy.
